Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a la ne change even if it is still some­
what far away . The faste r a vehicle approaches,
the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Veh icles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than
9 mph (lS
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot .
The
display will not tu rn on if you quick ly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are desig ned to detect the left
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti ­
cal for a lane change. For example:
- If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case , the
system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are driving through a curve . Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar sensors
c!:> fig. 82 with
stickers, deposits, bicycle whee ls or other ob-
Assistance systems
jects, because they will impair the function. Do
not use side assist when towing a trai ler. For in­
formation on cleaning, see
c!:> page 185.
A WARNING
=
- Always pay attention to traffic and to the
area around your vehicle. S ide assist cannot
replace a driver's attention. The driver alone
is always respons ible for lane changes and
similar dr iv ing maneuve rs .
- In some situations, the system may not
function or its function may be l imited. For
examp le:
- If vehicles are approaching or being left
behind very quickly. The disp lay may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles i n the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or author ized Audi
Service Facility check their funct ion .
(D Tips
- If the window glass in the dr iver's door or
front passenger's door has been tinted, the display in the exterior mirror may be incor­
rect .

A ppl ies to: ve hicles w ith a rea r parking sys te m /pa rking sys ­
tem p lus/rearv iew camera
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear park ing system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 83.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 83.
The rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or maneuver
¢ page 84.
_& WARNING
-Always look for traff ic and check the area
around your vehicle by looking at it directly
as well . The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
- Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed. Be especially cautious of small children
and animals.
-
- Always pay attention to the area around the
vehicle -using the rearview mirror, too.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
t io n.
- Make sure the sensors are not obstructed by
stickers, deposits or other materia ls. If they
are, the sensor function could be impaired.
82
For additional information on cleaning, see
¢page 185.
(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
- objects such as barrier chains, trailer draw
bars, vertical poles or fences
- objects above the sensors such as wall ex­
tensions
- objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor range. Note that you will no longer be
warned about th is obstacle.
@ Tips
- The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- external ultrasonic sources such as from
cleaning vehicles
- in heavy rain, snow, or thick vehicle ex­
haust
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- The sensors must be kept clean and free of
snow and ice for the parking aid to operate .
For information on cleaning, see
¢page 185.
- You can change the volume and pitch of the
signals as well as the display¢
page 87.
-Please refer to the instructions for towing a
trailer located in
¢page 88.

Intelligent Technology Electronic stabilization
control (ESC)
Description
Ele ctronic stabilization control (ESC) supports
driver safety . It reduces the risk of slipping and
improves d riving stability. ESC detects critica l sit ­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicator light b links in the instrument clus­
ter.
T he follow ing systems are integrated in the ESC:
Ant i-loc k bra king s ystem (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Brak e a ssist s ystem
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
unti l the dangerous sit uat io n is ove r.
Anti-Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin spinning and ad apts the force to the road
conditions . This makes it easier to start, acceler ­
ate and dr ive up hills .
Electronic differential lock (EDL )
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels ( if the veh icle is
equ ipped w ith all wheel dr ive*) . This function is
n ot available at higher speeds .
0 ~ In extreme cases, EDL automatically switches off
~ to keep the brake on the braked wheel from over-N
8 heat ing . The vehicle is still work ing correctly . EDL 0

will swi tch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by cha nging
t h e steer ing torque .
Selective wheel torque control
Se lective wheel torque control is used when driv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both wheels on the i nside of the
c ur ve are braked se lectively as needed. This al­
lows mo re prec ise dr iving in c urves .
Automatic post -collision braking system
The "automat ic post -collis ion braking system"
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an accident.
If the a irbag
contro l modu le detects a collision above a certa in
vehicle speed, the ve hicle is br ake d by the ESC.
The vehicle does not brake automatically if:
- the dr iver presses the acce lerator pedal, or
- the bra king fo rc e generated by the pressed
brake pedal is greater than the braking force
that would be in itiated by the system, or
- the ESC, the brake system or the veh icle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
phys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
gi n a cting to s tabilize yo ur vehicle, you
should immedi ately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk o f a collis ion.
- Please note the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre ­
vent co llisions - there is st ill a risk of acci­
dents!
89

Intelligent Technology
-Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
{D) Tips
-The ABS and ASR only function correctly
when all four wheels have a similar wear

condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working .
£SC turns on automatically when you start the engine .
Fig. 96 Center console : OFF~ button
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driv ing on rough terrain when much of the car's
we ight is lifted off the wheels (axle artic ula­
tion)
- Dr iv ing downh ill wh ile braking on loose g round
The ESC is designed to function in levels. Depend­
ing on the level selected, the ESC stabilization
function is limited or switched off . The amount of
stabilization control wi ll differ depending on the
level. For your safety, sw
itch the offroad mode off in
advance.

Hill descent assist
Appl ies to: vehicles with hill hold assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig. 97 Center console : hill descent assist butto n
• To switch the hill descent assist on, press the
~ button in the center console c} fig. 97. The
LED in the button turns on.
• Press the button again to switch it off. The LED
in the button turns off .
Hill descent assist brakes all four whee ls auto ­
matically in order to limit speed when driving ei­
ther forward or reverse on hills with a grade up to
approximately 50% .
When hill descent assist is on, the speed your ve­ hicle was traveling when it entered the hill is
maintained . It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist begins shortly after you start driv-
e '.:: ing and continues up to approximate ly 19 mph
N r--. (30 km/h) . T he driver can increase or decrease N .... 0 0 ::, (X)
Intelligent Technology
the vehicle speed within these limits by pressing
the accelerator or brake pedal.
However, there must be enough tract ion. Hill de­
scent assist
cannot function as expected, if for
example the hill is icy or if the surface is loose
¢,&. .
A blinking indicato r light. in the instrument
cluster will indicate if the system if actively regu­
lating a specific speed up to approximately
19 mph (30 km/h). The indicator light stays on
continuously when in the ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h) . The system is
then in ready-mode . This is indicated by the LED
in the button turning on. The system automat i­
cally switched off when you drive faster than 37
mph (60 km/h) . The LED will also turn off in this
scenario .
Hill descent assist is automatically activated un­
der the following conditions:
- the LED in the button turns on
- the vehicle speed is lowe r than 19 mph (30 km/
h)
- the incline angle is at least around 10%
A WARNING
-
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over­
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions .
- Hill descent ass ist may not be able to hold
your vehicle at a constant speed under all
conditions while dr iving on a hill (for exam ­
p le if ground under the vehicle is loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km) . They
must be "broken in" first . However, you can
IJ,,
91

Intelligent Technology
compensate for the slightly reduced brak ing
force by pressing firmly on the brake peda l. Avoid
heavy b raking during the break -in per iod .
Wear
Brake pad wear depends largely on the way the
veh icle is driven and on operat ing cond it ions.
This is especially t rue if you are driving frequently
in the city and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when br aking depend ing on the
speed, b raking force and outs ide cond itions such
as temperature and humidity.
Effect of water or road salt
I n ce rtain s ituations, fo r example after driving
through water, in heavy ra in, afte r ove rnig ht con­
densat ion or after washing your car, the braking
effe ct can be red uced by moisture or ice on the
b rake rotors and brake pads. The brakes must be
"dr ied" first with a few careful brake applica ­
tions.
At highe r speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The laye r of salt
on the brake rotors and brake pads must be worn
off first when t he brakes a re applied ¢ ,& .
Corros ion
L eaving the vehicle par ked for long periods of
time, low mi leage and avo id ing heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty b rake pads .
If you usually avoid heavy b raking or if there is
corros ion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and pads¢,&.
92
Brake system malfunction
if you no tic e th at the b rake peda l t ravel has sud­
denly gotten larger, then a brake ci rc u it may have
failed ¢.&. .
Low brake fluid level
When the b rake fluid level is low, malfunctions in
t h e b rake system may occur. The b rake fl uid leve l
i s e lec tron ically moni to red.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal. It only works when the en­
gine is runni ng ¢ ,& .
.8, WARNING
-On ly app ly the bra kes for the p urpose o f
cleaning the brake sys tem w hen road and
t raffic conditions permi t. You mus t not en­
danger other roa d users . This increases the
risk of an accident.
-
- Never let the ve hicl e roll whi le the engine is
stopped because t his increases the risk of an
accident .
(D Note
- Never let the brakes "rub'' by pressing the
peda l lightly when braking is not actually
necessary . This causes t he b rakes to over ­
heat and increases braking distance and
causes wear.
- Be fore driving downhill a long d istance on a
steep hill, decrease your speed and select a lower gear. This makes use of the engine
brak ing effect and relieves the brakes . If
you need to bra ke add itiona lly, bra ke in in­
te rvals and not cont inuous ly.
(D Tips
- If the brake booster is not working, you
must press the b rake peda l with much more
forc e than normal.
- If you retrofit your veh icle with a front spo il­
er , wheel covers or sim ila r i tems, make su re
